WELL-TILE-PLAGING TOOL.

Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed April 3, 1915. Serial No. 18,918.

To all whom it may concern .Be it known that I, Gnoncn H. CABGIN, acitizen of the United States, and a resident of Marcus, in the county ofCherokee and State of Iowa, have invented a new and ImprovedWell-Tile-Placing Tool, of which the following is a full, clear, andexact description.

This invention relates to a tool for placing well tiles in position, oneon top of another, and while the tool is especially adapted for thiswork it is not necessarily limited thereto.

The object of the invention is to improve and simplify the constructionand operation of tools of the character referred to so as to be reliableand eiiicient in use, comparatively simple and inexpensive tomanufacture, and so designed as to be readily manipulated.

A further object of the invention is the provision ofa tool adapted tobe placed within a tile and then to be expanded for gripping the latterfor lowering into a well, the tool having automatic means for efiectingits release from the tile as soon as the last previously laid tile hasbeen reached, the re leasing of the tool enabling same to be withdrawnwhile the tile is left in position.

A more specific object of the invention is the provision of simple andefiective means for locking the tile gripping elements in grippingposition and in conjunction there with an automatic device for unlockingthe said locking means so that the tool will be released from the tile.

With such objects in view, and others which will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth withparticularity in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of theinvention, and wherein similar characters of reference indicatecorresponding parts in all the views, Figure l is a perspective view ofthe tool locked in expanded position; Fig. 2 is a vertical section ofthe tool contracted; Fig. 3 is a detail view showing the parts of thelock ing device in locking position; Fig. 4 is a perspective view of thetool while carrying a tile and about in the act of laying the tile onthe lower one already laid; Fig. 5 is a plan view of the upper portionof Fig. 2; and Fig. 6 is a sectional view on the line 6-6, Fig. 2.

arms 3 of a spider or head 4, the hub of which is provided with :1depending tube or sleeve 5 that forms a guide for a sliding sleeve 6carrying a head 7 that is connected by hnks 8 with the arms or elementsA, which links expand or contract the tool by the sliding of the sleeve6 on the guide 5. Between the upper end of the sleeve 6 and the hub ofthe head 4:, and surrounding the guide 5, is a helical compressionspring 8' tending to force the sleeve 6 downwardly, whereby the tool iscontracted.

The device for expanding the tool includes means whereby the device isautomatically locked when the tool is expanded, and since the tool islocked provision must be made for automatically unlocking the tool fromthe tile when the tool and tile are lowered into a well and have reacheda point where the tile must be laid. The operating means includes ahand-actuated lever 9 of L-shaped form which is fulcrmned at 10 on oneof the arms of the head a, and at the elbow of this lever is pivoted alink 11, the lower end of which is suitably formedto connect with theupper end of a helical extension spring 12,

which spring has its lower end connected by a hook or equivalent device13 with the movable head 7. When the lever 9 is moved in a clockwisedirection, Fig. 2, for expanding the tool, the pivotal point 14 swingsan are around the pivot 10, and as soon as the pivot 14 passes to theright of a line extending through the pivot 10 and the lower end of thespring 12, the said spring contracts and holds the lever in lockingposition, as shown in Fig. 3, where the lever is engaged with a stop orlug 15. This lug is carried by a centrally disposed vertically movablerod 16 that is movable in the guide 5 and forms part of the automaticdevice for unlocking the lever 9. On the lower end of this rod 16 is across-head 17 connected by links 18 with two diametrically opposite armsA,

saidcross-head being secured in adjusted position on the rod 16 by a.set-screw 19, the adjustment being provided for adapting the tool fortiles of different diameters. When the tool is about to be laid on alower tile, as shown in Fig. 1, the centering extremities 2 by engagingthe lower tile are forced inwardly, which movement is communicatedthrough the links 18 to the rod 16, moving the latter upwardly farenough to throw the pivot 14, Fig. 3, to the left of the dead centerline passing through the pivot 10 and the lower pivoted end of thespring 12, whereby this spring contracts and unlocks the device, theunlocking being accompanied by the downward movement of the head 7 underthe expansive force of the spring 8', the result being that the tool isautomatically contracted so that it can be raised out of the well toreceive another tile. The tool can be suspended in any suitable manner,as, for

, instance, by hanger links 20 connected with ill a cable or rope. Ininserting the tool the elements A will be in the position shown in Fig.2, and then by operating the locking lever 9 the head 7 is raised, andthis in turn operating through the links 8 throws the elements Aoutwardly, as shown in Fig. 1, to grip a tile in the manner shown inFig. 4. The tile is now lowered into the well and finally the tool bystriking the uppermost tile already laid is automatically released.

From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the construction and method of operationwill be readily understood by those skilled in the art to which theinvention appertains, and while I have described the principle ofoperation, together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative and that such changes may be made when desired asfall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
